Mu mpera z'imyaka ya za 1980, Ubushinwa bwatangiye kubaka ibice bisize amabara bikurikiranye.Ibyinshi muri ibyo bikoresho byubatswe mu nganda zicyuma nicyuma hamwe n’imishinga ihuriweho, kandi ibikoresho byo gutunganya amabara byatumizwaga hanze.Kugeza mu 2005, ikibaho cyamabara yimbere mu gihugu cyari kigeze kuri toni miliyoni 1.73, bivamo ubushobozi burenze.Baosteel, Anshan Icyuma nicyuma, Benxi Icyuma nicyuma, Shougang, Tangshan Icyuma nicyuma, Jinan Iron nicyuma, Kunming Iron nicyuma, Handan Iron nicyuma, Wuhan Iron nicyuma, Panzhihua Iron nicyuma nibindi byuma binini bya leta inganda zibyuma zifite ubushobozi buke hamwe nibikoresho byurwego.Bakurikiranye kubaka ibara ryamabara hamwe nikoranabuhanga ryamahanga nubushobozi bwo gukora buri mwaka bwa toni 120000 ~ 170000.
Muri icyo gihe, umusaruro wibibaho bisize amabara washoye imishinga myinshi yigenga ahanini bifata ibikoresho byo murugo, bifite ubushobozi buke bwo gukora, ariko birihuta gutangiza no gushora imari mike.Ibicuruzwa bigenewe ahanini ibikoresho byo kubaka ninganda zo gushushanya.Byongeye kandi, umurwa mukuru w’amahanga n’umurwa mukuru wa Tayiwani nawo wageze mu rwego rwo kubaka ibice bitwikiriye amabara, ariko ibyinshi muri byo byibanda ku turere two ku nkombe.Kuva mu 1999, hamwe niterambere ryisoko ryibara ryamabara, umusaruro no gukoresha isahani isize amabara byinjiye mugihe cyo gukura byihuse.Kuva mu 2000 kugeza 2004, umusaruro wiyongereye ku kigereranyo cya 39.0%.Kugeza mu mwaka wa 2005, ubushobozi bw’umusaruro w’ibyapa bisize amabara byari hejuru ya toni zirenga miliyoni 8 / ku mwaka, kandi hubatswe ibice byinshi bisize amabara, hamwe n’umusaruro rusange w’igihugu urenga toni zisaga miliyoni 9 / ku mwaka.
Ibibazo biriho: 1 Nubwo ubushobozi bwo gukora plaque ya hot-dip yamashanyarazi kubikoresho byubaka ari binini, harabura kubura ibyapa byibanze nkibishishwa bishyushye bishyushye bitarimo indabyo za zinc na zinc alloy coil poil coil;2. Ubwoko nubwiza bwimyenda yo murugo ntibishobora guhaza neza ibisabwa.Igiciro kinini cyimyenda yatumijwe hanze igabanya irushanwa.Filime ya pulasitike isabwa ku isahani yamabara ya firime iracyakenewe gutumizwa mu mahanga, kandi harabura icyapa cyo mu rwego rwo hejuru gifite ibara ryinshi, imikorere, imbaraga nyinshi n'amabara meza;3. Ibicuruzwa ntibisanzwe, bivamo gutakaza umutungo cyane.Hariho amashanyarazi menshi cyane afite ubushobozi butarenze toni 40000 / kumwaka, kandi hariho ibibazo mubuziranenge bwibicuruzwa no kurengera umutungo w’ibidukikije;4. Hariho ibice byinshi bishya bitwikiriye amabara mubushinwa, birenze kure cyane isoko, bigatuma umuvuduko muke wibice byinshi bitwikiriye amabara ndetse bikanahagarara.
Inzira y'iterambere:
Ubwa mbere, gukoresha ibikoresho byujuje ubuziranenge bisaba ibisabwa hejuru kandi bisabwa hejuru yubuso, imiterere nuburinganire bwukuri bwa substrate.Kugira ngo ukoreshe hanze, nk'ururabyo ruto rwa zinc ruringaniye rushyushye-rushyushye rwicyuma hamwe nindabyo zitari zinc zishyushye zishyushye zishyushye, zinc alloy ishyushye-dip galvanised coil izamuka mugihe;Kugira ngo ukoreshwe mu nzu, nk'icyuma gisya, icyuma gikonjesha imbeho hamwe na coil ya aluminium.
Icya kabiri, kunoza inzira yo kwitegura no kwisuka.Hamwe nibikoresho bike nigiciro gito, byahindutse inzira nyamukuru, kandi bigahora bitezimbere ituze, kurwanya ruswa hamwe nibikorwa byo kurengera ibidukikije byamazi yo kwisiga.
Icya gatatu, iterambere ryimyenda mishya ni ugutezimbere poliester rusange, fluoride polyvinylidene (PVDF) hamwe na plastike sol kugirango ibone amabara meza cyane, irwanya UV, irwanya dioxyde de sulfure no kurwanya ruswa;Gutezimbere imyenda ikora nko kurwanya umwanda no kwinjiza ubushyuhe.
Icya kane, ibikoresho byigice biratunganye.Kurugero, imashini nshya yo gusudira, imashini nshya yo gutwikisha umuzingo, itanura ryiza ryo gukiza, hamwe nibikoresho byikora byikora.
Icya gatanu, tekinoroji yubukonje ikonje yahindutse inzira yiterambere kubera igiciro cyayo gito, isura nziza, ibyiyumvo bitatu-nimbaraga nyinshi.
Icya gatandatu, witondere gutandukana, gukora no murwego rwohejuru rwibicuruzwa, nkibibaho byimbitse bishushanyijeho ibara, "uruhu rwa grapefruit uruhu", ikibaho cyo gutwikisha amabara, ikibaho kirwanya amabara, ikibaho cyangiza ibara ryangiza, ibara ryinshi ryinjira mubushuhe ikibaho, n'ibindi
Ikigezweho muri iki gihe mu Bushinwa ni uko abakora amasahani asize amabara yita cyane cyane ku bwiza bwa substrate zikoreshwa mu gukora ubwabo mu gukora amasahani yometseho amabara, kandi bakaba bafite ibisabwa byinshi kandi biri hejuru kubikorwa byabo bwite, bigatuma amasahani asize amabara afite umusanzu mwiza mubikorwa byo gukora.Byongeye kandi, ibikoresho byo gukora amasahani yometseho amabara nabyo biratera imbere cyane, bigatuma amasahani yometseho amabara arushijeho kuba mwinshi mubikorwa byinganda, ntibizigama ikiguzi gusa, ahubwo binakiza abakozi benshi, Byongeye, hariho byinshi kandi ibicuruzwa byinshi bisize amabara, kandi irushanwa ryisoko riragenda rikomera.Kuzamura ubuziranenge bwibicuruzwa no kugabanya igiciro cyibicuruzwa byahindutse mubikorwa bisanzwe byabakora amasahani asize amabara.Ibicuruzwa bitwikiriye amabara byahindutse byinshi kandi bitandukanye.Ibibaho bitandukanye bisize amabara birashobora gukina ibikorwa byinshi bitandukanye, bigatuma isoko ryibara ryibara ryisoko rishimishije cyane.
